This pen scared me quite a bit when I first got it. It skipped a lot. It ran
scratchy. After a long process of priming and breaking in, this pen turned out
to be great! I can use any kind of short international ink cartridge I want.

Pros:
Writes nicely
Cute colors
Very fun
So customizable

Cons:
Took a lot of breaking in
Bleeds quite a bit (it could just be the ink I use)
